Reference divider
Reference divider input frequency
Drive level into CIN1 from external oscillator
Note
8. To simplify single ended drive there is a resistor between FIA and FIAB and another between FIM and FIMB. In this mode the inputs should
drive FIA or FIM with D.C. coupling and the other inputs FIAB and FIMB should be decoupled to ground by external capacitors.
